Deputies from the Norwalk Sheriff’s Station went to a public storage facility in the 10900 block of Firestone Boulevard Tuesday to follow up on a tip about a large quantity of illegal fireworks stored there. A Sheriff’s Transit Services Bureau explosive detection K-9 alerted to the suspected storage locker, which contained 91 cases of illegal fireworks.

The registered owner of the public storage unit is not in custody, but sheriff’s officials say a criminal case will be submitted to the Los Angeles County District Attorney’s Office for filing consideration.

Any item that explodes, rises in the air and moves about on the ground, or any fireworks not labeled “Safe and Sane” by the State Fire Marshal, is illegal in the state of California.
